Statements
The following statements allow the to specifically direct the process in alternative packages.

DOM editing

Attributes selection
Finding names, identification, values, colors, and other settings is possible via JavaScript.

Element selection

The code to seek an element via a collection of those elements present:

The code to add an element could be this (appending the body (HTML) element): Note: this will not work in an XML document. XML documents don't have the HTML Body tag/element.

Timers
JavaScript establishes two time oriented objects.
 * 1) setTimeout


 * 1) setInterval

Events
The following gives an example of catching a key event to describe it's code (via a label). It's extremely simple and may only work in FireFox or something similar. Better snippets can easily be found to suit numerous purposes. Try this example if you're unsure what Unicode numbers follow your keyboard strokes. A good detector is found below this page/link Detecting keystrokes. If you notice, it will operate differently in Firefox, Chrome, or IE, (for mathematical operators mostly).

Excluding IE
Internet Explorer will recognize a simple inclusion from within HTML comments: Some logic is allowed through the use of  for greater than (or   for lower than): This merely an HTML solution to include scripts that specifically apply within IE (or the opposite).

ActionScript
ActionScript is the scripting language in use in Flash website/movie development.

ActionScript isn't very different from JavaScript. It applies the same language style to a timeline application. And it offers several commands to work with movies. But, it essentially adopts the same ECMAscript requirements for it's language.

Developing with JavaScript
JavaScript is a standardized language best described by popular use. Alterations to the language need to be adopted. Deprecation of former code-practice is common in the standardization process. The community of developers is social. This means that they migrate to new instances of JavaScript usage. Information overload is expected for individuals attempting the intensive learning curve. New standards are adopted progressively so that programmers can migrate their assets. Most coders will attempt some restriction of their required skill-set. It's best to communicate/share via a project when producing larger developments. See: https://developer.mozilla.org/en-US/docs/JavaScript

Developing with React
React is a Javascript library built and maintained by Facebook. It is used for developing of web and mobile apps. React relies on Virtual DOM for updating the UI which sometimes creates performance issues.
